[Development] CyanogenMod porting

[abbradar]

I and some fellow developers (especially thanks manveru0, skywalker01, other users for testing, reporting and other help) are trying to port AOSS to our device, working with CyanogenMod 7 for now.
You can check out this thread, repositories, and this post for changelogs, bug reports and so on.
Github repositories:
https://github.com/abbradar
https://github.com/manveru0
Feel free to check them out and fork!

Current status of porting:
Working:

• Screen (w. touch features, w. backlight)
• Buttons
• Radio (w. 2G/3G, Internet is working)
• Bluetooth
• WLAN
• Rotate sensor
• Handset button
• USB
• Battery sensors
• Camera
• GPU acceleration

Not working:

• GPS (does not lock)
• Audio (both input and output, will be tough)
• Camcorder (because of audio)
• Storage-related (external SD not working, internal with no USB storage, vold misconfigured)
• USB tethering/MTP (will require some programming)
• Host access point (similar to USB tethering)
• Light sensor
• Buttons force feedback
• Contacts on SIM card

Not tested:

• Other sensors (compass, magnetic)
• HDMI (should not work, as logs say)
• FM radio (should not work)

Another bugs:

• CyanogenMod settings doesn't work (fixed by
• Random reboots sometimes
• Sometimes - very long resume from sleep (30 seconds approximately)
• Keyboard is very small
• Dialer is laggy (because of audio)
• USB connected notification is shown without USB cable attached
• APN database is not working (enter settings manually)
• Vibration strength is very weak

Regressions: (worked before)

• Nothing for now

Wow this sound really good. Thanks for your work. I write that i would support a cyanogenmod with a donation (and other people too). Maybe you can initate something in the gt9001 thread in the cyanogenmod forum.

jeahh, keep up the good workkk

 

[abbradar]

OK, I'll continue my work later this week according to ideas in the first post.

Owwwiiiii !!!! I like it !

 

[abbradar]

Made few modifications to the kernel to make its log readable. Further trying to make bootimage mount /system. By the way, isn't /system image size in my configuration too small? (~140MiB) Do we have some source of information on partition sizes?

 

[manveru0]

While helping manveru0 with developing of his awesome CWM mod and kernel, I've tried to compile CM for our device. So far, we have those problems as for now:
1) Resulting type of image - CM builds *.img files in output, and system/data/cache partitions, too - we should find some option in Makefiles to change output to raw ext4 image, as in Odin images. I was able to create ext4 image manually, but that is not an option for frequent builds, and I don't want to write a script if there is option avaliable (though, I think I will write it for now)
2) Booting. Right now, boot.img from builded CM loads adb, and I can send some basic commands to the phone, but it cannot mount /system and because of that "adb shell" doesn't work, so I cannot check what is going wrong during boot. My current idea is to insert /system/bin/sh into boot.img for testing.
I have nearly no time for work now because of university, but I will try to make some test builds later. We have all our work in github repositories:
https://github.com/abbradar
https://github.com/manveru0
So feel free to check them out and fork!

I comming back as soon as I have more time, see other posts

 

[abbradar]

After groking sources of Android's init for some time, it seems we should implement exporting partition table to /proc/mtd to continue or we'll have to modify lots of cyanogenmod's sources. Alternative to this is to try using stock binary "init".

Yeah man, keep on porting. I love CM Rom...

Finally! Thank you both YardE and manveru0 for all your efforts for developing something to i9001. I'm definately one of those willing to donate for your work!

 

[igor_999]

I'm definately one of those willing to donate for your work!

+1 to donating

 

[GuestK00250]

i love u!!!

 

[abbradar]

Let's wait with donating till we really have something usable ~_^. Okay, good news to you guys - I was able to build good enough bootloader to mount partitions! So we have adb shell and stuff now. The next step is to try to load actual system.

 

[abbradar]

I've also been able to found out format of out images (system.img and such) and there is utility to convert them to raw ext4 images - simg2img.
Looks like the first two tasks in porting were completed. ^_^

I was able to boot till CyanogenMod's splashscreen! \(^_^)/ It hang ups on it, though, but I can read error messages though adb now and shell is working.

 

[abbradar]

Oh god YES! I was finally able to boot it! Hurrray!

 

[crybert]

That sounds great! Perhaps you can post some screenshots to give a first impression to us ;-)

I was just uploading one. Made from my notebook web-camera, so quality is ****ty, but this is a proof-of-concept:

 

[abbradar]

This is results of first testing: nearly nothing works out-of-the-box, including sound, proper backlight, Wi-Fi/Bluetooth, video accelerator and phone. Looks like this will need lots of further tweaking, however, I'm glad I've got to make it this far! ^_^

AWESOME

dude you got it working everything else will fall in place sooner or later!!!!!! AWESOME!!!!

 

[abbradar]

Guys on Russian forum asked me for posting test build, so I'm uploading it on mediafire now. I'll repeat - this build doesn't have ANY practical usage, it's only proof of concept and having it on phone is nearly the same as having no phone at all..
